by FronczekHello people,
I've got this laptop not working for repairs, and as you can see something was done to it as you can see in the coils PL58XX (which I for some reason cannot find in the schematics...) The first FET (PQ201) was not an original part and a questionable one at that and the second one (PQ202) was shorted. Both are N-channel. Ordered replacements for them and replaced them after arrival. Now I have encountered another problem: there is no power at the second FET. By following the thread linked I got to the injection part. Applied 0.8V at 1.5A, but couldn't feel anything getting hot,...Technical discussions covering any type of laptop, notebook, netbook, tablet, or smartphone. Any and all brands and models welcome.

by smic717394Hi guys, I need a bit of help, I have a Asus Zenbook with motherboard UX533FD Rev 2.1. Connecting the laptop draws 30mah and not coming on, Measuring the coils I got the values below. Measuring in resistance all coils have normal values, cpu about 8ohm and the gpu about 5ohm but I guess its normal. Checking with the thermal camera, the only 2 chips that have a bit of heat signature are the U3501 (pd controller) and the U3001 that is the KBC. Now I guess the PD controller it's not the the problem because the battery is fully charged and trying to turn on on battery is the same.

by GcnewbieForgive me this is my first request for help on this forum, so if i've screwed up or not followed the rules i should have i apologise profusely.
I have a Dell Latitude 5570 that was randomly shutting down, on further investigation i found that the machine had been shutting down due to thermal events as noted by windows event viewer.
My investigations lead me to the dell diagnostics screen, where i found that there were two sensors out of range which had been causing the shutdowns, one of which was the GPU thermal sensor and the other the ambient sensor.

by sammus540I have a Vostro 3420 8H8K5R3-8FC8 that freeze at any attempt to enter bios password or the recovery master password received from dell. I do not have a clean BIOS image to flash.
And as luck would have it happened a couple of months ago right outside of the warranty period (Dec 2023) warranty expired in September. Any help or guidance is appreciated.-

by reassorThere is 2 sia ics and in 1 section where u see dots on the coils i have 2.2ohm there and there is no voltage on them at all.
Also i read in other topić how psu works on these tvs and when u pług it in there is constant 40w draw from wall. When I unplug display from tcon it drops 10w when I unplug tcon it drops another 10w (unplug done w/o power ).
I'm mostly sure its main board cpu cause no sygnał to turn on 24 volt for panel and its constant draw.
For now I'm just curios about these w coils . Could not find any datasheet for ic thats the lines go...1 PhotoYesterday, 11:06 PM -

by rumpumpel1I have a ThinkPad X270 (NM-B061) with the following error: the mainboard tries to start, the current goes up to 80 mA and then immediately drops back down to 20 mA. This is repeated every few seconds. Fortunately, there is a timing diagram at the end of the schematic. Starting from the top up to and including -PWRSW_EC it is all as shown in the diagram. Starting with -PCH_SLP_S4 you can see the periodic behavior, i.e. instead of the signal staying at 3.3V, it always drops back to 0. What conclusions can I draw from this behavior?
